I'm not sure that's quite the same thing - many of us will have taken advantage of similar hospitality at other clubs.The club welcome and actively sell corporate packages to away fans with seats located in the home areas.
They are asked to be respectful and not over celebrate, and in the main that happens.
Would fans prefer corporate income to go down in favour of No away fans other than the away end?
But in "General Admission", as the club refers to the non-hospitality areas, the unspoken rule is if you are in "the wrong end`' you sit on your hands and keep your mouth shut. You may still get rumbled, possibly if you're the only one not celebrating a home goal, but if you've been respectful then most will be OK with that.
